The Claim
In pregnant women during the third trimester, serum ferritin levels exhibit a weak inverse correlation with thyroid-stimulating hormone (TSH) levels, with a statistically significant p-value less than 0.05.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In pregnant women during the third trimester, lower levels of serum ferritin are associated with higher levels of thyroid-stimulating hormone (TSH).
See the scientific wording
In pregnant women during the third trimester, serum ferritin levels exhibit a weak inverse correlation with thyroid-stimulating hormone (TSH) levels, with a statistically significant p-value less than 0.05, suggesting that lower iron stores are linked to higher TSH concentrations in this population.
When iron stores are low, the thyroid gland cannot make enough thyroid hormone, so the brain sends more signal to the thyroid to work harder, raising TSH levels.
What the research says
1 studyIn late pregnancy, women with less stored iron tend to have slightly higher thyroid hormone signals (TSH), and this study found that link is real—not just by chance.
